NBAS gene

neuroblastoma amplified sequence

From NCBI Gene:

This gene encodes a protein with two leucine zipper domains, a ribosomal protein S14 signature domain and a Sec39 like domain. The protein is thought to be involved in Golgi-to-ER transport. Mutations in this gene are associated with short stature, optic nerve atrophy, and Pelger-Huet anomaly. [provided by RefSeq, Oct 2012]

From UniProt:

Involved in Golgi-to-endoplasmic reticulum (ER) retrograde tranport; the function is proposed to depend on its association in the NRZ complex which is believed to play a role in SNARE assembly at the ER (PubMed:19369418).

  • Short stature, optic nerve atrophy, and pelger-huet anomaly
  • Infantile liver failure syndrome 2

From UniProt:

Infantile liver failure syndrome 2 (ILFS2): A form of infantile liver failure syndrome, a life-threatening disorder of hepatic function that manifests with acute liver failure in the first few months of life. Clinical features include anemia, renal tubulopathy, developmental delay, seizures, failure to thrive, and liver steatosis and fibrosis. [MIM:616483]

Short stature, optic nerve atrophy, and Pelger-Huet anomaly (SOPH): An autosomal recessive syndrome characterized by severe postnatal growth retardation, facial dysmorphism with senile face, small hands and feet, normal intelligence, abnormal nuclear shape in neutrophil granulocytes (Pelger-Huet anomaly), and optic atrophy with loss of visual acuity and color vision. [MIM:614800]

NBAS mutations have been found in a multisystem disease affecting the liver, eye, immune system, connective tissue, and bone. Clinical manifestations include a progeroid appearance, short stature, slender bones, epiphyseal dysplasia with multiple phalangeal pseudo-epiphyses, cervical instability, myelopathy, elevated transaminases, hypogammaglobulinemia, reduced natural killer cells, Pelger-Huet anomaly of granulocytes, and in some cases retinal dystrophy and optic atrophy.
